N-octadecane is a colorless liquid and a white solid at low temperatures. Flash point (℃): 165; Melting point (℃): 28.18; Boiling point (℃) :316.1. Insoluble in water, soluble in ethanol, ether and methanol.
The uses of n-octadecane are as follows:
1. Used as phase change material, widely used in pharmaceutical cold chain logistics, phase change storage It can be used for temperature control of phase change microcapsules and electronic components in construction and textiles.
2. Gas chromatography stationary solution (maximum operating temperature 60°C, solvents are petroleum ether, toluene), separation and analysis of low-grade hydrocarbons.
3. Gas storage functions such as hydrogen storage and nitrogen storage.
